QoE Update — 2

## Added

- **`Spectator` use cooldown** (`UseCooldown` in skillsInfo.json, default 0.5s) — every press destroyed and recreated the camera prop, with no rate limit.
- **`SkillUtils.ClearCursesFor(playerIndex)`** — clears a leaving player's curse bookkeeping from both sides (as curser and as victim).
- **`SkillUtils.AnyCurseCapacity(player)`** — reports whether a player still has  any enemy left that is under the curse limit.
- **`Spectator.PlayerDisconnect`** handler.
- **`Thief`** added to the curse skill set.

## Changed

- **`CurseSkillPerPlayer` is ignored in GameMode 1 (TeamSkills), 2 (SameSkills) and 5 (Debug).**
- **Curse target menus no longer go empty.** When every living enemy is already at the limit, the menu falls back to the unfiltered list and the claim is forced through.
- `C4Camouflage` `MaxPerServer` -1 -> 1
